2 Claiins.

, This invention relates to a metal drum, and more particularly, to a metal drum having longitudinal tie rods co-acting between ends having deep annular recesses.

It is an object of this invention to provide a metal drum easily and inexpensively manuiactured.

It is a further object of this invention to provide a drum having annular ends having deep recesses therein.

It is another object of this invention to provide a metal drum having ends with deep annular recesses, said recesses being united by a plurality of tubular tie rods.

It is a further object of this invention to provide a drum adapted for packing any material, said drum having an easily disengageable head with bayonet lugs to engage lugs of a top annular end.

. It is a further object of this invention to provide a cover formed of two discs, the outermost disc having bayonet locking lugs and ,theA inner disc being adapted to engage a sealing ring upon application of pressure of the outer disc during` the closing operation.

It is a further object of this invention to provide a drum which is entirely closed, said drum having ends with deep annular recesses, said recesses being connected by tubular tie rods.

`These and other objects of this invention will become apparent upon reading the following descriptive disclosure taken in connection with the accompanying drawing, in which,

Figure 1 is an elevation view, partlyrin longitudinal section, showing a `drum having a detachable cover.

Figure 2 is a top view of the drum, partly in section, showing the manner of locking a cover of the drum to the top annular end,

Figure 3 is a sectional View of" an annular end and showing a reinforcing bead, and Figure 4 is a crosssectional view of atop end showing the manner of locking the cover to the lug of the said top end. i

Referring to the drawing; an annular bottom end I having a deep V-shaped radial crosssection peripheral recessed channel 2 therein is welded to a plurality of tubular tie rods 3. An annular top end 4 (see Figures 1"V and 4) having a deep V-shaped radial cross-section peripheral recessed channel 5 therein is integrally united to tie rods 3 at the line of junction of the inner and outer walls of the channel.

The recessed bottom end I may be provided with a concave inwardly disposed central section 5 on the inner wall of recessed channel 2, and is further provided with a tubular bead l on the outer wall of recessed channel 2. The walls of the annular recessed channel 2 may be tiered to effect greater strength, such a tier being in the inner Wall of the recess at point 3. The peripheral recessed channel E may be apertured at the points Where the tubes Zi are united there-to, so that an unobstructed passageway exists between the V-shaped recessed channels 2 and 5 so that liquid or air may be conducted from. one peripheral recessed channel 5 through the tubes 3 and then into the other peripheral recessed channel 2. The outer or exterior wall of the recessed channel 2 may be curved into the shape of a tube of circular cross section so that it forms the bead 'I thereby forming a solid and durable circumferential circular base which supports the weight of the drum and its contents.

Referring now to the top end 1i, this end is provided with a plurality of inwardly disposed locking projections 9 disposed in the outer wall forming the recessed channel 5 of said top end ll. The inner Wall of the recessed'end channel 4 is provided with a portion IQ of semi-circular cross section at its extremity adapted to receive a solid resilient sealing ring l! having a semicircular cross section and made for example from rubber or plastic. The outer wall of the top end 4 may be provided with a circumferential tubular bead I2 which bead substantially fully and cylindrically encloses a circular rod At the line of junction of the inner and outer walls of the recessed channel 5 the end l is provided with a plurality of spaced apart apertures, which apertures are disposed within the spaced :apart tubular tie rods 3.

The outer walls of both the bottom end l and the top end 4 are inwardly dented a short distance away from the line of junction of their inner and outer Walls of the respective recessed channels to accommodate a cylindrical drum body I3. This drum body is welded to the top end d at point I4 and to the bottom end I at point I5. The tubular tie rods 3 are also welded to the ends I and 4 about the orices in the respective annular members. The bottom of the container may be provided with anadditional reinforcing member I6 which may also function as a wear-plate,

said `wear-platebeing circumferentially disposed about the bottom bead l, which bead is initially enclosed by the curved surrounding extremity of the outer leg of end plate I.

The cover of the metal drum shown in Figure 1 has a top disc I'I having a flat cent-ral portion tremity 22 which extremity has a depending legV 23, said leg 23 being adapted to engage the at surface of the circumferential resilient sealing' ring Il. 1n closing the drum the cover placed on to the curved surface lil of the inner wall of the top drum member l with the lugs i9 out of register with the lugs 9. To close the drum into a sealing or a closed position'the top cover is rotated so that the lugs i9 engage the lugsil in rictional engagement. This rotation of the cover forces disc Il' downwardly against elevations 2i and 22 so that the leg 23 of inner disc 2G engages the sealing ring Il with a strong grip action due to the spring effect of the distortions of said elevations 2| and 22.

The top disc l? may be provided with lifting lugs 2d which lugs have an aperture therein for engaging lifting means such as grappling hooks and the like. The body I3 of the drum may be provided with a plurality of spaced apart parallei-disposed pairs of grooved recesses 25. In the embodiment of the invention illustrated in Fig- `ure 1 Vthere is provided two V-shaped circular bands or tires 2@ and 21, each of these bands having a V-shaped cross section of such a height that the apices of said V-shaped tires 2t, 2i are disposed on a line above the beads l and i2 of the drum, thereby effecting two points of rolling contact of the drum with a level door. Clearly the body I3 of the drum on being rolled on a floor is not subject to contact with the iloorand any consequent distortion. The bands or tires 2% and 2l Yare disposed about the body wall i3 in spaced relationship and contact the iloor. These bands 25 are' provided with flat surfaces 23 which extend outwardly from the V-shaped portion. These flat surfaces 28 are indented into the recesses 25 of the metal drum i3. The bands 26 and 2l may be welded to the body wall i3. Clearly the indentations made in the flat surfaces 28, pressing the metal of said iiat surfaces into the recesses 25, function in the sense of keying the bands 26, 2i' immovably in place relative to the drum surface i3. The drum of this invention may be made of substantially all commercially available metals but it is preferably made of aluminum. The sheet forming the drum body i3 has a longitudinal weld 29. rIhe end members l and l are united to the body element I3 by means of a girth weld 30.

While this invention has been described by means of an illustrative embodiment, it is apparent to those skilled in the art that many variations of this embodiment will become readily apparent upon reading the description of this invention taken in combination with the illustrative drawing. However, these non--inventive variations of this invention are intended to be embraced within the scope of this invention appearing in the claims hereinafter.

Having described my invention, what I claim and desire to secure by Letters Patent is as iollows:
